When you remember that one kid you had a crush on from the Garrison and told your gay dad all about, so instead of getting rejected or making it awkward, you pretend you hate him.

It backfires when you have a bonding moment and he pretends he doesn’t remember it.
It’s a rivalry. You know? Lance and Keith, neck and neck.

A competion in East Rockaway High School that takes place between the months of January and March, involving students in grades 9 through 12. Rock Rivalry consists of many competitive and creative events, such as a sports night, arranging/directing a short musical production, and creating both a stand and mural to reflect the theme of each respective performance. Nassau Community College studies have found that the competition causes a great deal of inter-class and intra-class tensions. In addition, the only award for winning said event is a silver cup that the class can only keep for 2 days, usually resulting in copious amounts of alcohol consumption for both winners and losers alike. For about 2 months, this is all the high school will be talking about. East Rockaway High School has had this tradition every year since 1936

An argument or fight between two or more stupid people. Especially immaturely and in front of a group of people.
Those two dumbasses, Ben and Jared, both liked the same girl, so they formed a retard rivalry and began yelling at each other like fucking five-year olds.

The retard rivalry between the homosexual HSM fanboy and the emotard went over the edge and eventually the two began viciously attacking each other.

A connection shared between people who can't stand each other's guts but don't dislike each other either. Typically amongst Pokémon trainers, die hard melee fans, and cucumbers.
Red and Gary have a healthy friendly rivalry.

the worst cinema motion picture release of all time, released in 1990. The storyline and plot are badly written, the acting is crummy to the hilt, the comedic elements and jokes are a bit on the sadistic nature - hell, even the obligitory sex scene is so phony you won't believe the directors and producers put it in like they did. It stars Kirstie Alley who was then starring in the cool TV series Cheers.
Don't waste your time with seeing Sibling Rivalry. It's absolutely depressing that this shit was actually promoted and advertised as a comedy.
